Biosynthetic Polymers as Functional Materials
The synthesis of functional polymers encoded with biomolecules has been an extensive area of research for decades. As such, a diverse toolbox of polymerization techniques and bioconjugation methods has been developed. The greatest impact of this work has been in biomedicine and biotechnology, where fully synthetic and naturally derived biomolecules are used cooperatively. Despite significant im...
متن کاملPVT Properties of Polymers for Injection Molding
PVT (Pressure-Volume-Temperature) properties of polymers are important for both engineering and polymer physics. Fig.1 shows the typical PVT diagrams of an amorphous (a) and semi-crystalline polymer (b). PVT diagram describes the specific volume as a function of pressure and temperature. Specific volume increases with the temperature increasing. There is a thermal transition in the polymer. The...
متن کاملPOTENTIAL WOUND HEALING MATERIALS FROM THE NATURAL POLYMERS -A review
Wound healing represents a major health burden and the variety of wound types has resulted in a wide range of wound dressings with new products frequently introduced to target different aspects of the wound healing process. These wound dressing biomaterials play an active role in the healing process, thus accelerating the process. An ideal dressing should achieve rapid healing at reasonable cos...
متن کاملInjection Molding of Plastics from Agricultural Materials
OBJECTIVE DOE Chicago Operations %ice The objective of this research was to conduct a systematic study to relate injection molding parameters to properties of blends of starch and synthetic polymer. Blends of normal (25 % amylose) and high amylose (50 and 70% amylose) corn starch (containing between 60 and 70 % of the mixture by weight) and synthetic polymer were used in this research. Two diff...
متن کاملTetrahydrofuran (co)polymers as potential materials for vascular prostheses.
Polyethers were studied as potential materials for vascular prostheses. By crosslinking poly(tetramethylene oxide)(PTMO) with poly(ethylene oxide)(PEO), hydrophilic networks were obtained containing PTMO as well as PEO. Attempts were made to reduce the crystallinity and melting point of PTMO because of the required elastomeric behaviour at body temperature. Compared to non-crosslinked PTMO, c...
